摘要： The disclosed embodiments relate to the design of a system that converts sunlight into electricity. During operation, the system concentrates the sunlight onto a front surface of a selective absorber, wherein the selective absorber comprises a semiconductor material having a band gap capable of absorbing most spectral components of the sunlight (such as intrinsic silicon), and wherein the concentrated sunlight causes heat to build up in the selective absorber. Next, the system uses heat obtained from the selective absorber to drive a heat engine, which converts the heat into mechanical energy. Finally, the system converts the mechanical energy into electricity.

摘要： A travelling wave thermoacoustic piezoelectric apparatus capable of generating electrical energy from heat energy is provided. The travelling wave thermoacoustic piezoelectric apparatus includes a hosing with two ends connected by an inertance component, a porous stack, a resonator, and a piezoelectric bimorph. The housing comprises a compressible fluid and has a first portion and a second portion. The first portion receives heat energy from a heat source for creating a temperature gradient between the first portion and the second portion. A cold heat exchanger within the second portion is positioned at one end of the porous stack. The compressible fluid traverses between the first portion and the second portion through the porous stack and the inertance component to generate travelling acoustic waves. The travelling acoustic waves resonate with the resonator for generating acoustic energy. The piezoelectric bimorph positioned at an end of the resonator opposite to an end of the resonator connected to the second portion, oscillates based on the acoustic energy for generating the electrical energy.

摘要： This invention provides heat engines based on the structure of internal combustion engines and employs a gaseous working fluid without combustion. The heat engine comprises at least a piston and cylinder assembly and each cylinder has at least an associated heating chamber with a heat exchanger unit being disposed therewithin. The chamber may have at least a chamber valve to establish or block the flow of the gaseous working fluid between the heating chamber and cylinder space. The engine is adapted to operate on cycles that enable heat transfer from a heat source to the working fluid while being enclosed within the heating chamber and provides substantially increased heat transfer duration before the power stroke. Therefore the engine may produce sufficiently high power output with reasonably high thermal efficiency.

摘要： A thermodynamic engine is configured to convert heat provided in the form of a temperature difference to a nonheat form of energy. Heat is directed through a heating loop in thermal contact with a first side of the thermodynamic engine. A second side of the thermodynamic engine is coupled to an environmental cooling loop in thermal contact with an environmental cooling device. The thermodynamic engine is operated to dispense heat from the second side of the thermodynamic engine through the environmental cooling loop into the environmental cooling device. Operation of the thermodynamic engine thereby generates the nonheat form of energy from the temperature difference established between the first side and the second side of the thermodynamic engine.

摘要： A solar power conversion system using a plurality of engines to convert solar energy to electrical energy. The plurality of engines are supported adjacent to a housing having a single thermal cavity. The cavity is provided with solar energy from a solar collector. Each of the engines can be turned off or regulated to maintain an optimum operating temperature for a common heater head in communication with each of the engines. Therefore, the power conversion system can be regulated for variations in insolation to maintain an optimum temperature in the heater head. Therefore, increased life cycle energy efficiency of the power conversion system can be obtained.
